The typical dosage for adults for an allergic reaction is 120mg daily. If you have chronic hives, the typical dosage is 180mg daily. In children two to 11 years old, the typical dosage to treat hay fever is 30mg twice daily. In children six months to two years old, the typical dosage to treat chronic hives is 15mg twice a day, in children two to 11 years, the typical dosage is 30mg twice a day. Fexofenadine should be used with extreme caution in children younger than six months.
